In the Queen’s Diamond Jubilee year this book’s title sounds opportunistic, but Piers Brendon could reasonably point out that it is a sequel to a book he wrote three decades ago called Eminent Edwardians, which deliberately echoed Lytton Strachey’s classic work, Eminent Victorians. The aim of all three books, he says, is ‘to unlock’ the age through ‘vignettes’ of four key figures of the period.
